<p>To use the transforms, you must have the
<a href="https://www.elastic.co/subscriptions" class="ulink" target="_top">appropriate license</a> and at least one
<a class="xref" href="transform-setup.html#transform-setup-nodes" title="Transform nodes">transform node</a> in your Elasticsearch cluster. If Elastic Stack
security features are enabled, you must also ensure your users have the
<a class="xref" href="transform-setup.html#transform-privileges" title="Security privileges">necessary privileges</a>.</p>

</h4>
<p>To use transforms, there must be at least one node in your cluster with
<code class="literal">xpack.transform.enabled</code> and <code class="literal">node.transform</code> set to <code class="literal">true</code>. By default, all
nodes are transform nodes unless you explicitly change these settings or set
<code class="literal">node.data</code> to <code class="literal">false</code>.</p>
<p>If you want to control which nodes run transforms, set <code class="literal">node.transform</code> to
<code class="literal">false</code> on some nodes.</p>
<p>For more information, see <a class="xref" href="transform-settings.html" title="Transforms settings in Elasticsearch">Transforms settings</a> and <a class="xref" href="modules-node.html" title="Node">Node</a>.</p>

<p>The Elasticsearch security features provide <a class="xref" href="built-in-roles.html" title="Built-in roles">built-in roles</a>
and <a class="xref" href="security-privileges.html" title="Security privileges">privileges</a> that make it easier to control

<p>To <em>view</em> the configuration and status of transforms, you must have:</p>
